1.編寫登錄腳本-autologin：
#!/bin/bash
/bin/login -f <username> #你的用戶名
將autologin文件移到到/usr/bin/下,並且用chmod +x autologin設置可執行權限
2.修改/etc/init/tty1.conf
修改前：
# tty1 - getty
#
# This service maintains a getty on tty1 from the point the system is
# started until it is shut down again.
start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]
respawn
exec /sbin/getty -8 38400 tty1
修改后：
# tty1 - getty
#
# This service maintains a getty on tty1 from the point the system is
# started until it is shut down again.
start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]
respawn
exec /sbin/getty -n -l /usr/bin/autologin -8 38400 tty1
重啟系統后，則系統會默認用設置好的用戶自動登錄
